Drilling Jets

[HondaBoy]

ok, well i'm taking my scrap carb apart and looking it over what stuff. so i was thining, would it be worth while to drill out the jets just a bit? i hope what i took pix of was the jet, this is out of the secondary bore pictured.

you can drill them out, but what i did was a little diff.
if you remove the glass window in thew fuel bowl, you will see a two jets. I drilled those. it was pain in the ass. after that my car was running way rich so i had to put spacer in the middle of the carb. that helped to lean out the mixture.
I wouldn't recomend drilling them.
if you want real tunnable carb, go with weber. it probably would be best upgrade for the money.

yeah, maybe thats not such a good idea, but an idea none the less. anyways, i think i'ma say f'that. i am planning for a dual webber sidedraft setup though.

those are not the main jets, the jets are in the float bowl, not the booster venturi.

ah, i see. well i think i've decided that unless i want the take the carb apart again, i may just forget about doing that.

make sure you face the tube the right way when you stick it back in, it has a cut/angle to the opening.

yeah, i think that one is fubared, but its from my parts carb so i'm not too worried. i think i'm just going to leave my carb thats on the car alone and not mess anything up trying to mod it like that since its my daily driver and runs fine as is.
